Accuracy NTC Temperature Sensor , Platinum Resistance Temperature Detector

Description

M-series PRTDs are designed for large volume applications where long term stability, interchangeability and
accuracy over a large temperature range are vital. Typical applications are Automotive, White goods, HVAC,
Energy management, Medical and Industrial equipment.

The measuring point for the nominal resistance is defined at 8mm from the end of the sensor body.
